A germplasm release that exhibits a high degree of resistance to bacterial angular leaf spot disease caused by Xanthomonas fragariae. Origin: developed by J.L. Maas, T.C. Gouin, S.C. Hokanson, and J.S. Hartung, USDA–ARS, Beltsville, Md. Earliglow × SG-26 (F. virginiana); cross made in 1979; selected in 1980; tested as 80-4-38. Fruit and Tree: Clone appears typical of native populations in terms of morphology, runnering, flowering responses, and fruit development however, fruit is notably larger than most wild clones of F. virginiana. High degree of resistance to infection by highly virulent strains (Xf3, Xf6, 1425, and ATCC 33239) of X. fragariae. The type of resistance exhibited is hyposensitive in that inoculated tissues do not rapidly develop into necrotic areas and bacteria do not spread form inoculated tissues into healthy tissues. In a cross with highly susceptible cultivar, transmitted resistance to 4% to 18% of its progeny. Fruit:
